Abstract
A sheet feeder includes a separation roller, a retard roller, and a return latch. The separation roller rotates in a forward direction to separate a sheet and transport the separated sheet in a sheet transport direction. The retard roller forms, together with the separation roller, a nip point and rotates in a reverse direction to return a sheet in a direction opposite to the sheet transport direction. The return latch moves from a retracted position to a protruding position to return a sheet remaining after separation by the separation roller to a position upstream of the nip point in the sheet transport direction. The return latch, when at the retracted position, is retracted from a sheet transport path and, when at the protruding position, protrudes to the sheet transport path.
